Alarm Systems; and I do declare the followa ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in fire alarm systems.

- The primary object of the invention is to provide a fire alarm which isautomatically operable when a fire breaks out in a build ng to notify the fire department of the location of the building and also to'sound an alarm" to the occupants of such building.

Another object of the invention is to improve upon systems of thisnature by the provision of an extremely simple, and inex pensive combination and arrangement of parts and one whichwill be eflicient and reliable inoperation, and well adaptedto the pn ose for which it is designed.

ith these and numerous other ob]ects in view, the invention consists of certain novel features of construction and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of the application and in w ich similar reference characters designate like parts throughout the several views Figure 1 is a diagrammatic representation of a fire alarm system arranged in accordance with this invention;

Fig. 2 is a diagrammatic representation of a portion of the apparatus used in connection with the system;

Figs. 3 and 4 are views of the opposite sides of the switch and telephone operating wheel;

Fig. 5 isa longitudinal sectlonal'view through the casing of one of the thermostatic switches; an

Fig. 6 is a cross sectional view of the same taken substantially on the plane indicated by the line 6-6 of'Fig. 5. 1 7 Referring more particularly to the drawings, the letter A designates a four story building on each of the floors b of -which is arranged an electric circuit 1 including a number at thermostatic switches 2 arranged in multiple, and an electric hell or gong 3 arranged -inseries. The circuits are connected n multiple with the conductors 4 and -5 of an" electric circuit which runs to the basement 0 of the building A; the conduc tor 4 being connected to one of the terminals" of an electric light ensign-6 arranged in front of the building while the' honductor 5 1s connected'to 'the pole 7of a double throw two bladed switch "8. The other terminal of the lamp 6 is connected by a conductor 9 to l the blade 10 of the switch 8, and the other blade 11 of the latter is connected to one ofthe line wires 12. The other line wire 13 is connected to'the pole 14: of the switch 8. To the poles '15 and 16 of this switch are connected conductors 17 and 18' respectively, the conductor 17 running to one of the brushes of an electric'motor 18-while the conductor-18 is-connected to the above mentioned conductor 4 leading to the lamp 6. The other'brush of the motor 19 is connected by means of a wire 20 to' the relatively fixed contact of a switch 21, the movable member of whichjs electrically connected with the line wire 13 by a short conductor 22.

Geared to the motor 19 by a suitable train of gears 23 is a shaft 24, one end-of which carries a beveled gear 25 which meshes with a beveled pinion-26 carried on the shaft of the turn table 27 of a phonograph. Geared to the shaft 24 by a set of reducing gears 28 1s a shaft 29 on which is mounted a wheel 30 having on one side thereof a cam'31-which engages the switch 21 and throws it to openedposition, while on the other side 'of the wheel 30 is a cam groove 32 which en-' gages and operates the switch arm 33 of a telephone 34; The transmitter 35 of the telephone is disposed adjacent preferably in 95. alinement 'with the horn 36 of the above mentioned phonograph so that the soundproduced by the phonograph will be transmitted over the telephone. The undulations 'on the phonograph record 37 are such-that a mechanical voice will be produced explaining that a certain-building on Each of these tlirnlfistatic switches 2 com;

prises a hollowcylin rical ,casingi38 which is fastened to the wall or ceiling' in any suit- 106 able manner, and which is provided over its open or .front side with a transparent c'ov mg 39. In this casing 38 is mounted a lug 40 to which the movable blade 41 of the switch is pivoted. This blade 41 is normally 11o held out of engagement with the fixed con- I tact 42 of the switch against the tension of its spring 43 by means of a his; wire 44, one

end of the/latter being connectedto the blade 11 while the other ergd is connected to abar 45. which extends transversely across the casing 38. a

vThe conductors which connect each of the switches 2 to the circuits 1 are connected as is obvious to the lugs 40 and contacts 4-2 of the switches.

I Normal y, all ofthe switches are open, theblades-IO andfll1of the switch 8 are in engagement withthe poles 7 and 15, the

switch 21 is closed, and the telephone switch arm 33 is maintained in raised position by the cam slot 32 so that the circuit through the phone isopen. Now should a tire break out inabuilding the heatthereof will cause the fuse wireH of the switch or switches 2 locatednear the fire to melt and close the respective cn'cuitl so'that current will pass "from'the line wire 12 to and through the blade. 11 of the "switch 8. through the wire 5 to the above nientioncd circuit 1, through said circuit, -wire 4, lamp 6, wire 9, blade '10 of the switch 8, wire 17, motor 19, wire 20,-switch21, and wire 22 to the other line wire 13'. Current thus'being supplied to the motor 19 will cause the same to revolve and operate the phonograph. The wheel will also be put in motion and the cam groove 32 will pass'out ofengagement with the tele-'.

' to rotate very slowly, the table-of the phonograph, however, rotatingrapidly. The ratio of the-gearing 'lS such that the entire message on {the record 3? will be reproduced while the wheel 30 is making one revolution. As this wheel revolves, .the cam 31 will engage the blade of the switch 21 and the cam groove 32 will engage the telephone switch arm 33fand simultaneously open the switch 2-1 and raise the arm 33. The circuit. being thus broken will stop the rotation of the motor.

If it is desirable to keep the lamp 6 burning so that the fire department which has been autox'natically summoned can readily asccrtainwhich building the tire is in, the switch 8 is manually swung into the other direct ionas soon as the motor 19 has stopped. The current will then pass through the lino wire 12. blade 11 of the switch 8, wires 18 and 4, lamp (3. wire 9, blade '10 of switch 8 and line wire 13. It is tobc understood that. the switch 8 is operated by hand.

After the device has been once operated, it. is again set by' placing a new fusewirc in throwing the switch H so that its hladcs 1U and '11 engage the poles 7 and 15.

From the foregoing description, taken in connection with the accompanying draw ings. the construction, use, and operation of the invention will be rcadilyunderstood without a more extended explanation. As various changes may be made without departing from the spirit, of this invention it is to be understood that I do not wish to be limited to the construction shown and-described other than'as claimed.
